Exchange 2007 OAB issue

Environment:
- Email Server: MS Exchange 2007 SP1 RU5 (SCR)
- Windows Server: Windows Server 2003
- Client: MS Outlook 2007

Issue:
- MS Outlook inability to download OAB

Description:
Microsoft Exchange offline address book
Not downloading Offline address book files. A server (URL) could not be located.
0x8004010F
- The above error is logged on the Sync Log when perform OAB download from client end.

Troubleshooting:
- Increase loglevel for OAB generation:
set-EventLogLevel -Identity “MSExchangeSA\OAL Generator” –Level Expert

- The following errors are found on Application logs:
1)Event ID 9395
Category: OAL Generator
Type: Warning
OALGen is running on a CCR node which does not have registry value 'System\CurrentControlSet\Services\MSExchangeSA\Parameters\ServerName\EnableOabGenOn ThisNode' or it is not set to this node name. offline Address book generation will not be performed.

2)Event ID: 9109
Category: OAL Generator
Source: MSExchangeSA
Type: Warning
Description: OALGen encountered error ffffffff while initializing the offline address list generationprocess. No offline address lists have been generated. Please check the event log for more information. - /o=GlobalExchange/cn=addrlists/cn=oabs/cn=New OAB3)

3)Event ID: 9334
Category: OAL Generator
Source: MSExchangeSA
Type: Warning
Description: OALGen encountered error ffffffff (internal ID 5000498) while generating address list" . Check other logged events to see if this is a serious error.  - /o=GlobalExchange/cn=addrlists/cn=oabs/cn=New OAB

Next Step:
To check the following:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters\<ServerName>\EnableOabGenOnThisNode

By default, the EnableOabGenOnThisNode value is the name of the CCR node that was installed first. This node is also known as the primary node. OAB generation or OAB updates may fail if one of the following conditions is true:

    The EnableOabGenOnThisNode registry entry is missing.
    The EnableOabGenOnThisNode registry entry contains an invalid name. For example, the registry entry contains the name of a server that is no longer the active node of the CCR cluster.

OAB Generation on a cluster server fails with event id 9395 or 9396
http://blogs.msdn.com/b/dgoldman/archive/2007/02/08/oab-generation-on-a-cluster-server-fails-with-event-id-9395-or-9396.aspx

How To Fix

This is an expected error if the ‘primary’ CCR node is temporarily unavailable, so just make sure it is back online ASAP. Otherwise, the following registry key needs to be in place and contain valid cluster node name: HKLM\System\CurrentControlSet\Services\MSExchangeSA\Parameters\Server-Name\EnableOabGenOnThisNode ="ThisNodeName".

NOTE: Make sure that you updated the registry value on the CCR node to be the name of the CCR node.

So if i understand you have the ServerA it works fine but not on ServerB ?
If yes did you edit the registry on ServerB ? If Yes did you reboot the server after that ?
